Devise a Newton iteration formula for computing R^(1/3) where R > 0. Perform a graphical analysis of your function f(x) to determine the starting values for which the iteration will converge. I found the newton iteration to be                      Xn+1 = (2/3)Xn + (R/3)Xn^2. How do I find the starting values graphically?
